Power: The power handling specification (180 watts peak) is only valid when using a high-pass crossover, 1.8 kHz and 12 dB/octave minimum.
Crossovers: The system includes two passive, high-pass crossover networks. The slope is 12 dB/octave and the crossover point is 3.5 kHz. A switch on the side of each crossover allows tweeter level adjustment to account for the car interior and tweeter placement, choose 0dB (no attenuation) or -2dB. The input and output wires are attached; the 30″ input wires are not terminated and the 10″ output wires have quick-slide terminals that mate with the wires attached to the tweeters. Adhesive backed pads and zip ties are included to mount the crossovers.
Crossover Dimensions:
- Width: 2⅞”
- Height: 1″
- Depth: 1¾”
